What you are seeing is the Check Engine Light. It is on because the computer has detected a problem with the emissions system on your Accord. Have the ECU (computer) scanned with an OBD2 scan tool. This will retrieve the code that has been set which will tell you what part is being effected. After this has been repaired the technician will reset the check engine light. If the car is not running right attend to this immediately. If the car is running great then you do not have to rush. Just get it fixed as soon as you can.
